Spring is a highly modular, distributed, object-oriented operating system. This paper describes the goals of the Spring system and provides overviews of the Spring object model, the security model, and the naming architecture. Implementation details of the Spring microkernel, virtual memory system, file system, and UNIX emulation are supplied.

In information bases following semantic and object-oriented data models logical names are used for the external identification of objects. Yet the naming schemes employed are not “natural” enough and several problems often arise: logical names can be ambiguous, excessively long, unrelated to or unable to follow the changes of the environment of named object. In natural language, similar problem...

Naming game simulates the evolution of vocabulary in a population of agents. Through pairwise interactions in the games, agents acquire a set of vocabulary in their memory for object naming. The existing model confines to a one-to-one mapping between a name and an object. Focus is usually put onto name consensus in the population rather than knowledge learning in agents, and hence simple learni...

Previous studies have shown that young children selectively attend to some object properties and ignore others when generalizing a newly learned object name. Moreover, the specific properties children attend to depend on the stimulus and task context. The present study tested an attentional account: that children's feature selection in name generalization is guided by non-strategic attentional ...

Sound naming schemes for objects are crucial in many parts of computer science, such as database model-ing, database implementation, distributed and federated databases, and networked and distributed operating systems. Over the past 20 years, physical pointers, keys, surrogates and object identiiers have been used as naming schemes in database systems and elsewhere. However, there are some pers...

In the paper we try to summarize the weaknesses of the CORBA Persistent Object Service standard we felt were most significant while designing and implementing a Persistent Object Service compliant with the standard. The issues discussed in detail include: underspecified semantics of operations, underspecified functionality of POM, lack of "compound persistence", reusability of other services (r...

The effects of two cueing treatments, Phonological Cueing Treatment (PCT) and Semantic Cueing Treatment (SCT), were examined with three chronic speakers with aphasia. The effects of treatment on action naming were measured with the use of single-subject experimental designs. The participants had received PCT and SCT to improve object naming in a previous investigation and had responded positive...

Distributed object systems (DOS) are usually implemented as middleware which repeats and undoes a signiicant amount of work performed by the underlying operating system 3]. This introduces overhead and leads to distinct, incompatible middleware implementations. Therefore, basic mechanisms are not usually shared. If mobility and replication rely on common techniques and mechanisms no matter the ...

We have previously reported the performance of a patient (NL) who could recognize objects, but appeared to lack knowledge of their orientation. These results were interpreted as evidence that NL had isolated access to a viewpoint-independent (ventral stream) object recognition system. However, because NL's responses on naming tasks were not timed, it was not possible to establish whether he sho...
